Specification of Letters Patent.

To all whom it may concern:

Be it known that L'CHARLES MORGAN, a citizen of the United States,residing at Freeport, in the county of Stephenson and State of Illinois,have inventeda new and useful Improvement in Molders Flasks, of whichthe following is a specification.

My invention relates to certain new and useful improvements in moldersflask, and is fully described and explained in the specification andshown in the accompanying drawings, in which Figure 1 is a perspectiveview of my improved flask; Fig. 2 is a longitudinal section showing theparts in one position; Fig. 3 is a view similar to Fig. 2 showing theparts in another position; Fig. 4 is an elevation of one of the fittingswhich embody the novelty of my construction Fig. 5 isa top plan of thesame, and Fig. 6 is a section in the line 6 of Fig. 4.

Referring to the drawings, A is the cope and B is the drag of my flask,while C is the pattern-plate which is used therewith. The drag hassecured to its two ends handles D, each of which has projecting upwardlyfrom it a triangular pin d preferably cast integral therewith and sodisposed as to be removed endwise a short distance from the plane of theside of the drag so that a correspondingspace is left between the pinand the cope as illustrated in the drawings. The pattern-plate has onits two ends plates 6 which project beyond the edges of the flasksections and have secured to them, or if desired, made integral withthem, patternplate handles E which are shaped so as to surround the pinsd and guide the pattern plate to position. The cope has secured to itsends cope-handles F, which surround the pins d to guide the cope toposition, these handles having in the preferred form of constructionplates f or thin webs of metal which lie between the pins and the copeproper, so that the pins are completely and accurately surrounded.

The construction as thus far described is not materially different fromthat which has heretofore been used in devices of this character. It isfound, however, that in the use of flasks of ordinary construction it isnot easy to drawthe cope accurately and smoothly and the molds arefrequently damaged, particularly when the patterns are deep.

termine the correct line of movement. This result is accomplished bysecuring to the cope-handle F two vertically adjustable ears 9 whichform pivots for a separating handle G. This separating handle is made inthe form of a U, the curved end of which forms a handle and thefurcations of which are pivoted between their ends to the ears 9 as setforth. The free ends of the separating handle bear rollers g which restupon the pattern-plate as seen in Figs. 2 and 3, the material of thecope being cut away to receive these rollers and the ends of theseparating handle. With the device so constructed, when it is desired todraw the cope the operator places the heels of his hands upon theprojecting flanges of the copehandle, and his fingers under theseparating handle and then by contracting his hands draws the outer endsof the separating handle upward, so that the cope is positively wedgedaway from the pattern-plate. As this action takes place it is evidentthat any oscillation of the cope about an axes extending from one handleto the other is impossible, because of the two-point contact whichoccurs at each end between the separating lever and the pattern-plate.It is of course true that one end of the cope could be drawn before theother if desired, but, owing to the efficient manner in which theseparating force is applied, and the increased accuracy with which thecontracting muscles of the hands can be used, as compared with themuscles of the entire arms which are used in normal practice, the twoends of the cope can readily be elevated simultaneously, and at equalspeed so that there is no possibility of the mold being damagedindrawing. After the cope is drawn the pattern-plate is rapped and drawnin the usual manner, and owing-to its relatively light weight and thefact that it is loosened by rapping before it is drawn the provision ofspecial means for insuring the accuracy of drawing it is not of greatimportance, although it is evident that analogous means could. ifdesired, be provided for separating the pattern-pIate from the drag, orin cases of great difficulty it would be possible toadopt any of-theusual-pattern-drawing mechanism for assuring a correct movement of thepattern-plate. It is of course evident that the invention here shown isnot necessarily usedin con nection with a device having a pattern plate.

If ordinary separated patterns are used the separating lever will bearranged to bear directly upon the drag as shown in Fig.1, in

which figure it will be seen that there is no.

the spir't of my invention, and I do. not ini tend therefore, to limitmyself to the specific form herein shown and described.

What I claim as new and desire to secure by Letters Patent, is:

1. The combination with a flask-section, of a pair of handles therefor,and fingeroperated levers for the handles each engaging the surface uponwhich the flask-section rests in two points in separate lines wherebywhen operated simultaneously the flask-section will be elevated, all itsparts moving in straight lines. a v

2. The combination with a flask-section, of a pair of handles adaptedthereto, a U- shaped lifting handle, the furcations of which are pivotedbetween their ends to the Copies of this patent may be obtained forhandle and the free ends of which bear upon the" surface upon which theflask-section rests to elevate the fiasksection.

3. The combination with a flask-section, of ap'air of handles adaptedthereto, a U- shaped lifting handle, the furcations of which areadjustably plvoted between their 7 ends to the handle and the free endsof which bear upon the surface upon which the flask-section reststoelevate the flasksection.

4. As .an article of manufacture, a handle adapted for attachment to aflask-section or other article used vin making molds and which requiresto be moved in drawing the pattern, said handle having attached to it afinger-operating lifting lever adapted when operated to move the handleand the part attached thereto in the appropriate direction.

5. As an article of manufacture, a handle adapted for attachment to aflask-section or other article used in making molds which requirespattern, said handle having attached to it, a lifting lever providedwith two engage.- ment-portio-ns whereby when operated the handleandpart attached thereto will be tobe moved when in drawing the c wprevented from oscillat-ionabout the axis vand will be elevated.

-In testimony whereof, I have hereunto set my hand this third day ofNovember 1911, in the presence o-ftwosubscribing witnesses.
